INTRODUCTION
1.2ANAMORPHIC LENS
DLP™ projectors use a small device called a DMD™ (Digital Micromirror Device) to create the video image. DMDs are designed in aspect ratios ranging from 4:3 (standard) and 16:9 (widescreen), to 5:4 (digital cinema). Understanding that more and more home theaters are designed using 16:9 or cinemascope projection screens (similar to your local Cineplex's), Runco has developed an anamorphic lens system to make the 5:4 DMD fully compatible with a home theater that has 16:9 and 2.35 screen formats.
The Runco Anamorphic Optical System elevates the image quality of a 16:9 picture to a higher level. This system consists of two components; one being the controller and the other the anamor- phic lens. The first component is Runco's award-winning Vivix™ VHD™ Ultra Controller with 10-bit processing which is used to scale the video signal to mach the native resolution of the pro- jector. The second part utilizes one of three anamorphic lenses that optically stretch the image to a 16:9 or 2.35 aspect ratio.
The advantages of using the anamorphic lens system is that it takes advantage of the entire mir- ror array on the DMD™ resulting in a higher resolution picture. The result is a high-resolution picture in a big screen format for the home theater. Another benefit of employing all the mirrors on a DMD™ is 25% greater light output for an increase in picture brightness. Runco's industry- renowned controller helps to trigger the electronic corrections for the stretched image and pro- vides four geometrically correct aspect ratios - 16:9 widescreen, letterbox, 4:3 and VirtualWide™. HDTV is also geometrically correct and has higher resolution. The Anamorphic optical systems include an Anamorphic lens, the lens mount assembly, and an Anamorphic Vivix™ Controller. The Anamorphic Optical System is the ultimate way to maximize resolution and will significant- ly shorten the throw distance of any Video XTreme™ series projector it is used with. Consult the specification sheet of the projector for specific throw distance calculations.
